Abstract
A redundant power supply system so contrived that, upon occurrence of a fault in any one power unit, the other power unit is capable of performing relief power supply to a load. The power supply system comprises an AC-DC converter for converting an AC voltage to a DC voltage, and a plurality of power units connected in parallel to the output side of the AC-DC converter. Each of the power units includes a power source for feeding the load with a stable DC output corresponding to the DC voltage; a fuse connected to the input side of the power source for cutting off a power line; a coil connected in series to the fuse; and a capacitor connected between a line, which is disposed between the fuse and the coil, and another line between the output side of the AC-DC converter and the input side of the power source.
